F.E.A.R.-PHAN

Yes this is a F.E.A.R. set, this works best with a level 25 Donphan(Lowest possible level for him) and is even better with Sand support, he is the new Aron! You will want minimum IVs in every stat except Attack, his stats should be: 80 Hp, 96 Attack, 65 Defense, 35 S.Attack, 35 S.Defense, 27 Speed on PO he can be lvl 1 though. Endeavor is for lowering the opponent down to your HP. Ice-shard is Priority in case you are up against a Pokemon that is not immune to sand or you are no on a sand team. Roar is for switching a Ghost type away. Rapid-spin is for getting rid of hazards.

Now Donphan is commonly used as a spinner. But let's take a little initiative here and try out a different set. Donphan's attack stat is a base 120. Let's abuse that sucker attack stat with Choice Band

Earthquake is STAB and super powerful. Head Smash is realllllly powerful coming off that Attack stat, even with recoil. You can add some wish support for the guy if you want. Chansey would work well. Ice Shard is priority and for hitting dragons like Salamence. Seed Bomb and Superpower is your choice, Superpower offers more coverage all around but maybe you want Seed Bomb to hit pokes like Gastro and Jelli. Now the poor guy is pretty slow, but with Sturdy and that Bulk he can do pretty well for himself. Again with Wish support from Chansey or others you can play him out again and again, reviving sturdy every time. Give it a try, you might be surprised. I know I was.

Donphan holds the Smooth Rock, making Sandstorm last for eight turns. It deals damage to most opponents, but not you. Plus, it raises his evasion by 25%. It can dodge, while we keep attacking with the help of a sandstorm. Nice and easy! Tell me what you think please!

This is a set that is supposed to be a sweeping set after some baton pass setting up ( Preferably +2 Atk +2 Def and wish when switching in)
Earthquake is there for standard reasons, Protect gives free lefties heal, ice shard is donphan's standard priority and Knock off cripples similar sets and any Mega Gengars or Gardevoirs floating about. Protect or Knock off could be replaced with Rapid spin, Rock slide or Stone edge as well.
